I have no opinion.
When I installed Windows 10 on a 2005 computer, I also helped some others with the same model [and the same hardware components].
My computer's Windows 10 performance was satisfactory. Some of the others reported very slow Windows 10 performance. Some others reported that Windows 10 was altogether unusable.
We never identified any difference between my computer & theirs, between my drivers & theirs or between the upgrade procedures we had all used.
So I no longer ever have an opinion about the likely performance of any computer in any OS.
Yes. They all do. They all get monthly Cumulative updates that include all the security updates. They also get updates for minor things such as .Net framework.
I still think there was some special circumstance affecting your previous experience.
There is only speculation about the possible Windows 12 project. There are no facts.
All the best,
Denis
